tracheophyte

The poorly preserved C. hemisphaerica is placed as the most basal tracheophyte.

The strand of conducting tissue contains simple tracheids, making this a vascular plant (tracheophyte).

The only significant basal tracheophyte in this habitat is the spikemoss Selaginella balfourii.

Tracheophyte Tracheophyte, a member of the largest and most varied group of plants.

The other former "rhyniophytes", such as Horneophyton and Aglaophyton, are placed outside the tracheophyte clade, as they did not possess true vascular tissue (in particular did not have tracheids).

One other former rhyniophyte, Aglaophyton, is also placed outside the tracheophyte clade, as it did not possess true vascular tissue (in particular did not have tracheids), although its conducting tissue is more complex than that of the Horneophytopsida.
